How to play?

Playing is easy!

To play, simply send the desired amount to one of the LuckyBit game addresses!

To play, copy the address into your wallet, using either the clipboard button or scan the QR code:

you can find the addresses of the games next to the game bars

all addresses start with

1Lucky

followed by a letter indicating the game color

Next, select the amount you want to play. For your bet to be valid,

the amount that you send must be at least equal to the minimum amount...

...and at most equal to the maximum amount of the game you are playing

you can find the minimum and maximum amounts next to the game bars

That's it, wait for your bet to appear at the top of the game area!

Valid bets

Your bet is valid if it respects the minimum and maximum limits of the game. Few seconds after
you have sent your bet from your wallet, you will see your coin falling out of the pipe at the top of
the LuckyBit game area. The color of the coin will match the game you have selected.
The coin will follow a (provably fair) random path through the game area
until it falls into one of the multipliers of its corresponding game.

LuckyBit immediately sends back to you your initial amount multiplied by the multiplier that
your coin attained. When your bet initially goes out of the LuckyBit pipe, a new line is added on top
of the table on the front page and shows some information for
your bet.
You can also verify all relevant information for every past bets in the
bet browser (always accessible
at the bottom of the front page).

Invalid bets

Bets might be invalid because the amount is too small or too large, according to the limits of the
game that you selected. If a bet is invalid, LuckyBut simply returns the bet to you immediately.
Your invalid bet will not be visible in the game area, but you can see it in the
bet browser.

Good to know

You can highlight your own bets by entering your bitcoin address into the box located at
the top-right of the game area. If you do so, a special sound will indicate bets that come from your
address. All other bets will be displayed semi-transparent. Additionally, you will see your last
five bets in your personal table.

The box located at the top-right of the game area also features a chat that you can use to
chat with other players. See you there!

You can hover the falling coins or the multipliers with your mouse to get more info.

Some more technical details

Transaction fees

Bets:
For player protection, LuckyBit will only instantly process bets that have been sent
with priority fees and are not at risk of being double-spent. In order to ensure
instant processing, make sure that payments to your wallet are are confirmed and
that you are using sufficiently high fees.

Payouts:
When paying out, LuckyBit includes a standard fee to reward miners.
Of this fee, 0.0001฿ comes from the player's payout while
anything above 0.0001฿ is entirely paid by LuckyBit.

Very large wins

Very large wins might require a manual intervention to pay out. In this case, the operators of LuckyBit
will be notified automatically and the payout will be done in a matter of hours.
Note that LuckyBit always holds enough coins to pay
the maximum possible earning that players can win, several times.

Suspicious transactions

LuckyBit reserves the right to delay bets whose transactions
are "suspicious" (based on a proprietary algorithm).
This delay can extend up to few minutes (maximum one block confirmation anyway).

It is our primary concern to be helpful and responsive, please contact us at

Frequently Ask Questions

Does LuckyBit have a faucet?

Yes, we have an official faucet, and it's probably the most exciting in the world, no kidding.
Check it out on luckyb.it/faucet/.

How can I check if my bet was processed by LuckyBit?

Go to the bet browser, and copy the
transaction ID of your bet in the search field.

Why my bet does not show up immediately on LuckyBit?

In case of a non-standard transaction, LuckyBit waits for one confirmation
before processing your bet. Most likely the fee of your transaction is too
small. Another (more rare) case is that one output is smaller than 5460 satoshis.

Both cases are visible by hovering the small triangle warning on the
"Estimation Confirmation Time" on blockchain.info with your mouse.
As soon as your transaction confirms, your bet will appear, just be patient!

My payout transaction isn't found on block explorers!

If this is visible next to
your payout, then your payout transaction was sent successfully.
If you can't find this transaction on a block explorer, please note
that they sometimes slower than us in picking up transactions, so just be patient.

Also, most block explorers such as tradeblock.com
are quite unreliable regarding unconfirmed transactions, so we advise you to wait for
the payout transaction to confirm.

I got a large win, but did not receive my payout immediately as usual.

Congratulations! :)
In case of large wins, we need to authorize the payout manually.
You can expect to get your payout within 12 hours maximum, typically less.

How does the chat lottery work?

After a bet plays, there is a small chance the lottery bot will wake
up to award a prize in the chat room. When this happens, a person that
was recently active in chat will be randomly selected to receive a
gift! To claim your prize, you must post your address
and the answer to the question within 60 seconds. The address you post
must also have been used to wager at least 0.01฿ on Lucky Bit within
the past 24 hours (exceptions: moderators can post any address, and
anybody can always use the tip jar address provided by the bot).

What is the shiny BONUS coin?

The "sparkling" coin bonus is a reward for players that is the
equivalent of a 1% site rakeback (may vary from time to time). All
bets have a small chance to win a bonus, although the chance is
greater for bets of at least 0.01฿. Bonus prizes can be up to 200% of the wager,
and are automatically added to your game's result.

Why is this page taking so much CPU?

It is the price to pay for fancy javascript animations. We are working on improvements!

The origins of LuckyBit

The type of game used by LuckyBit is quite old. It is commonly called a "bean machine" or a
"Galton box" after Sir Francis Galton, who was the first to describe the game in one of his books. A more
recent incarnation of Galton's box was "Plinko", a popular game on the TV-show "The price is right".
It is also the same concept as Pachinko games, a popular type of casino machines in Japan.

Your odds in LuckyBit

The odds for our games are a weighted sum over all multipliers of their numerical value multiplied by
the probability to fall into them.

The multipliers values are such that your odds are higher than
98.24% for each game.

You can also hover each multiplier with your mouse to get more information, among other things you will see the probability to fall into it.

For your convenience, this is the probability B
for a coin to arrive at the k's multiplier, counted from the side to the center (the side being k=0):

You can also find reliable information on the distribution of falling coins in the
Wikipedia article on the topic.

Lucky Bit is provably fair

Of course! :)
This is how it works:

The key that LuckyBit uses to determine the "lucky moves" of a bet, and thus the winning amount,
is changed every day;

The key of a given day is made public after midnight of the next day;

The respective hashes of all keys, past and future, have been
published and prove that LuckyBit uses the correct key for each day;

Nobody can modify this file, as its hash is recorded in the blockchain
as of 10th of September, 2013;

You can verify each bet in the bet browser, which is
also accessible at the bottom of the main page.

Need more technical details?

Your lucky moves are determined using a hash of the following string:

<tx_id>:<vout_id>:<secret_key>

, where:

<tx_id>

is the transaction id of your bet as assigned by your wallet.
(This data is controlled by you.)

<vout_id>

is the rank of the output of your bet within the transaction's
list of outputs. (Rank starts at 0 and is controlled by you.)
This produces different lucky moves for each bet if you play several bets
within a single transaction.

<secret_key>

is the secret key of the day. It is unknown to you
at the time of playing, but the hashes of all keys have been are published in advance, so nobody can
modify these keys. The day of your bet is determined by the moment LuckyBit receives your bet's
transaction. (Typically 1 to 10 seconds after you sent it.)

From the hash of

<tx_id>:<vout_id>:<secret_key>

, LuckyBit takes the
binary representation of the last 2 bytes and read it from the left side. The bits determine
your lucky moves: A

1

translates to a right move, a

0

to a left move. For instance, if the hexadecimal
hash ends with

ffff

, your coin would always go right
as the binary string would contain sixteen

1

and no

0

You can easily verify that your lucky moves were correct by computing the hash of the string

<tx_id>:<vout_id>:<secret_key>

of your bet.
There are many websites that allow you to do this, for example:

The key of each day is made public after midnight (UTC). LuckyBit can prove that nobody changed this key afterwards
because the hashes of all keys, past and future, have been published in this file:
http://luckyb.it/secret-key-hashes.txt

The file that contains all key hashes has itself the following hash:

e45fb03ae911b267615bc923803bc553adb0e3dd6c9e47c939073f30ec912a63

You can compute the hash of this file as follows (on Linux/Mac):

curl -s http://luckyb.it/secret-key-hashes.txt | shasum -a 256 -t

Using the hash of this file as a bitcoin private key, it produces the
following bitcoin address:

1L85BxKU6J169kM934PQyV52maHmE86cFc

. We have sent a transaction to
this address on the 10/09/2013 (included in block 257126). You can verify this on any block explorer, for example:

Note on wallets

Compatible wallets are wallets that allow you to receive bitcoin from the address(es) you sent from.
This is not the case with online wallets that use a single bitcoin address for several users.

Examples of compatible wallets:

Blockchain.info

Bitcoin-Qt/Bitcoind

Armory

Electrum

Multibit

Android bitcoin wallet

Examples of wallets that are not compatible:

Exchanges such as Xapo, Coinbase, Bitstamp etc.

Shared wallets of other gambling sites

Online wallets that send from a common address for all users

In general, any service that uses a shared wallet for all its users

If you're not sure if your wallet is compatible, test it by sending a bet with
the minimum amount to one of our games and see if
you get something in return.
